Electroless Nickel Plating on Magnesium Alloy

he inherent lightness and good strength-to-weight ratio of T magnesium has focused attention on increasing applications in aerospace and allied fields. Its density is two thirds that of aluminum-a conventional structure material for aerospace. Magnesium has one drawback: It is prone to atmospheric corrosion. Further, because of its high chemical affinity for aqueous solutions, it is categorized...

Preparation of Ni-Co Alloy Foils by Electrodeposition

Electrodeposition of Ni-Co alloy foils on titanium substrate was performed in an acid chloride-sulphate bath. The influences of electrodeposition parameters such as current density, temperature, pH value, cobalt sulphate and saccharin concentration on composition and current efficiency were investigated in detail. The morphology and the microstructure of deposits were analyzed by SEM and XRD, r...

Investigations of Surface Dissolution on Fatigue Crack Nucleation in Ni - 22 Cr - 2 Fe Alloy

Ni-Cr-Fe alloy specimens were fatigued in a hydrochloric acid solution cell at pH 5.6 ±0.1. Results show that the number of surface slip bands forming, extending, and widening increased with the number of cycles. Results also indicated that, initially, cracks initiated as transgranular features but took on intergranular forms as the number of cycles increased.

Ni-Co Alloy and Multisegmented Ni/Co Nanowire Arrays Modulated in Composition: Structural Characterization and Magnetic Properties

Design of novel multisegmented magnetic nanowires can pave the way for the next generation of data storage media and logical devices, magnonic crystals, or in magneto-plasmonics, among other energy conversion, recovery, and storage technological applications. In this work, we present a detailed study on the synthesis, morphology, structural, and magnetic properties of Ni, Co, and Ni-Co alloy an...
